MOLD.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed December 19,1904. Serial No. 237,530.

To all whom it may concern.-

Be it known that 1, JOHN F. SCHWARTZ, a citizen of the United States, residing at Alma, in the county of Gratiot and State of Michigan, have invented a new and useful Mold, of which the following is a specification.

This invention relates to means for molding building-blocks, preferably those constructed of concrete, in the form of artificial stones, though the invention undoubtedly has certain features that are useful for other purposes of an analogous nature.

One of the principal features of the invention resides in the means for withdrawing the blocks formed in the mold from the faceforming wall, so that the danger of marring or otherwise injuring the exposed ornamental faces of such blocks is reduced to a minimum.

Another feature relates to means which will permit the ready expansion and contraction of the molds in order that blocks of different sizes may be made therein, and still another advantageous feature resides in the general structure of the mold, the same being comparatively simple, capable of withstanding rough usage, and being convenient and handy to operate.

Two embodiments of the invention are shown in the accompanying drawings.

Figure 1 is an end elevation of one of such embodiments with the mold in position to be filled. Fig. 2 is a cross-sectional view through the same, showing the mold after the block has been moved out of coaction with the faceforming wall. Fig. 3 is a front elevation of the structure when in the position shown in Fig. 1. Fig. 4 is a rear elevation of the same. Fig. 5 is a longitudinal sectional view therethrough with the parts as shown in Fig. 2. Fig. 6 is a detail horizontal sectional view through one of the end walls and a portion of the face-forming wall. Fig. 7 is a detail perspective view of one end of a block constructed in the mold. Fig. 8 is an end elevation of a modified form of construction, and Fig. 9 is a vertical cross-sectional view therethrough.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated in the first six figures a base is employed comprising end legs 10, supporting a platform 11, said end legs having upstanding ears 12, constituting 13, having at one end an actuating-lever 13. A support in the form of a frame having angularly-disposed portions 14 and 15 is journaled on the shaft 13, said shaft being located at substantially the juncture of said angular portions 14 15. The frame portion 14 is provided with a longitudinal guideway 16 and also: with transverse guideways 17, the latter being located contiguous to the ends of the frame. having transverse webs 19, is fitted against the inner side of the frame portion 14 and is secured in place by bolts 20 passing through the ends of said wall and through clips 21, located against the outer face of the frame portion 14 and bridging the guideway 16, these clips and bolts thus being adjustable toward and from each other. The face-forming Wall 18 preferably has a configuration to represent undressed stone, though this configuration may be changed as desired. Standards 22, located at substantially right angles to the frame portion 14 and the face-forming wall 18, have their inner ends located against the inner face of said frame portion 14, being adjustably secured thereto by means of bolts 23, that pass through the transverse slots or guides 17. are provided with hooks 24, in which are journaled pintles 25, carried by the ends of a swinging mold-wall 26, this mold-wall being ordinarily held against its swinging movement by latches 27, pivoted upon the free ends of the standards and engaging over lugs 28, carried by the ends of the wall 26. The frame portion 15 of the support constitutes a slideway, upon which is mounted a movable blocl -s11pporting wall 29, the inner edge of which is thus movable toward and from the face-forming wall 18, as will be apparent by reference to Fig. 2. This wall is adapted to be moved by means of earns 30, carried by the rock-shaft 13 and bearing against the in ner edge of said wall 29, the said wall 29, furthermore, constituting a support for end walls 31, that preferably have central curved portions 32, provided with integral projectin lugs 33, terminating short of the edges of said end walls and forming handholds in the ends of the block, said block being designated 34, and one of said hand-holds being shown in Fig. 7. The inner edges of the walls 31 fit in seats or grooves 36, formed in the adjacent bearings in which is journaled a rock-shaft l face of the face-forming wall 18, as shown'in The outer sides of the standards A face-forming wall 18,

ICO

Fig. 6, while their outer edges bear against cleats 37, carried by the inner side of the swinging wall 26.

The operation of the structure above described may be briefly outlined as follows: The blocksupporting wall 29 is moved inwardly, the end walls 31 are placed in position with their inner edges engaged in the seats 36, the swinging wall is locked against movement to the standards with the cleats 37 engaged over the outer edges of said end walls, and the entire support, comprising the frame portions 14 15, with the walls, is then swung to the position shown in Fig. 1. It will, of course, be understood that suitable cores may be employed, if desired. The material is then shoveled into the open top of the mold, and after being tamped said mold is swung to a horizontal position or, in other words, with the wall 26 uppermost. This wall is then released or detached from the standards 22, and the rock-shaft is then turned with relation to the support 14 15. The cams thereupon bearing against the inner edge of the wall 29, which now constitutes the support for the block 34, said wall and block are bodily moved from the faceforming wall, as shown in Fig. 2. At the same time the end walls 31 are moved out of .coaction with the face-forming wall, and thus being released can be taken off. The block is therefore supported solely upon the wall 29, which is bodily removed from the mold with the block upon it and substituted by a new board, thus placing the mold in condition for immediate use. Because of the adjustable mounting of the clips 20 and bolts 21 a shorter or longer face-forming wall may be substituted for thatshown for the purpose of forming blocks of difier'ent lengths, and in like manner by adjusting the standards 22 the thickness of said blocks may be varied as desired, and these are features of considerable importance, as they afford convenient means for making blocks of difl erent sizes and shapes. I This structure constitutes efficient means for molding bricks or buildingblocks, and it will be observed that it has all the advantageous features set forth in the preliminary portion of the specification.

A simpler form of the invention 'is illustrated in Figs. 8 and 9, wherein a base is employed comprising end legs 10, carrying, in this instance, an immovable support in the form of angularly-disposed frame portions 1 1 and A rock-shaft 13 is journaled in this support, and a face-forming wall 18 is secured to the frame portion 1 1 by means of adjustable clips 20 and bolts 21, similar in all respects to those above described. Standards 22 are 'adjustably mounted on the support by means of bolts 23, which in this instance pass through transverse guideways in the frame portion 15*. The standards 22 have hooks 24 in which are journaled the pintles 25 of a mold-wall 26 the same being normally held against its swinging movement by means of latches 27*, car ried by the standards 22 and engaging lugs 28 at the ends of the wall 26 A blocksupporting wall 29 is slidably mounted on the frame portion 15 and is operated by cams 30 carried by the rock-shaft 13 EX- cept for the swinging action of the mold as a whole it will be observed that this modification or embodiment of the invention operates exactly the same as the above-described and has the same advantages.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
